VF-TLP systems using TDT and TDRT for kelvin wafer measurements and package level testing

Very fast transmission line pulse (VF-TLP) systems described in the literature are time domain reflection (VF-TDR) configurations. Using other TLP configurations, VF-TLP systems can provide new capabilities. A wafer level Kelvin probe system was derived from VF-time domain transmission (VF-TDT). A test fixture board (TFB) using VF-time domain reflection and transmission (VF-TDRT) enables VF-TLP package level testing.
